Anemia and Bariatric Surgery: Results of a National French Survey on Administrative Data of 306,298 Consecutive Patients Between 2008 and 2016.
Article in Obesity surgery, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 27 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundBariatric surgery (BS) has grown exponentially in France, and long-term anemia due to micronutrient deficiencies has become common.
objectivesThe objective of this study was to assess the long-term risk of anemia after BS and to investigate the factors associated with the occurrence of this complication. MATERIALS AND
methodsData from the French National Health Service database on patients who had undergone gastric bypass (GB), sleeve gastrectomy (SG), or adjustable gastric banding (AGB), between 2008 and 2016 were extracted. Only patients with a primary intervention were considered.
resultsData from 306,298 patients (143.733 SG, 79.188 GB, and 36.413 AGB) were analyzed. Overall, 12.930 of them (5.0%) had a diagnosis of anemia due to micronutrient deficiencies as main diagnosis or related diagnosis at time of a hospital stay between 2008 and 2016. In multivariate analysis, GB surgery, female gender, age younger than 52 years, and 25-OH vitamin D deficiency were positively associated with the occurrence of anemia whereas hospital procedural volume was negatively associated. The risk to be diagnosed with anemia after BS was 13.0% after a GB, 5.6% after a SG and 4.0% after an AGB (Log-rank p < 0.0001). The hazard ratio for anemia after GB compared to SG was 2.0 (95% CI 1.9-2.1), adjusted for age and gender.
conclusionIn France, between 2008 and 2016, 5% of patients had anemia after BS. The risk to develop anemia was 2-fold higher after a GB than after a SG. Young women should be particularly aware of this long-term risk.
